When 3D ultrasound is used there are 3 steps that should be considered separately; volume acquisition, Glass-body with colour Doppler and Rendering.
Firstly, 3D volume acquisition is a key technique that uses ultrasound when examining the fetal heart. This technique contains digital information of the cardiac structures and their spatial arrangement; therefore cross-sectional views can be obtained at any desired orientation, direction and depth. An example of this is the reconstructed cardiac volume displayed as a single hypothetical real-time cardiac cycle played in a cine loop, which can be played in slow motion or stopped at any time for a detailed analysis of specific parts of the heart, this is shown below in figure 1. According to Springer written in Echocardiographic Anatomy in the Foetus (2008)
Studies on multiplanar analysis from a cardiac cycle at a remote station using STIC (slow acquisition of image slices) which takes an average of 7.5s-15s volume acquisition were shown to be reliable in assessing the different cardiac planes, in screening studies and in evaluating fetal cardiac anomalies, using a volume for an internet link evaluation are emphasized as well, allowing potential for a second opinion in the future, this technique using ultrasound allows doctors and surgeons the ability to see into the foetuses heart and allow them to have detailed image of the heart and see if there are any problems and if so allow them to operate precisely and efficiently. 3D volume acquisition allows for safer and more deta...

...ar septal defect, also this has helped demonstrate the calibre and relative position of the great arteries and other congenital heart diseases, these examples allow doctors and surgeons to prove weather or not the foetuses has any defects inside the heart or any abnormal growths, allowing the foetuses to be operated on earlier rather than later when the heart may not be inoperable. These are other key facts that make ultrasound a great nomination for the New Zealand Medical Journal to be the most important piece medical equipment in use today.
In conclusion, volume acquisition, Glass-body with colour Doppler and Rendering are key techniques used in echocardiography through the use of ultrasound. The finale point is perhaps the most important as rendering proves if foetuses have defects within the heart and this allows doctors and surgeons to operate and save lives.

- ... The development of sonography as a career is likely to increase with many employment openings around the word. Training is offered by hospitals, colleges and schools. Most employers favor job applicants who have completed formal training program at college or university, particularly for the ones who have no related experience working in healthcare (Study 2016). To practice, diagnostic medical sonography a two-year associate degree or a four-year bachelor’s degree is required (Summary). Coursework for the program includes physics, anatomy and physiology....

- The dream that I most desire in life is to become a Diagnostic Medical Sonographer. I’ve always had an interest in the inner workings of the human body, but I also value life, and care for others, and my happiness is the happiness of others. Although this career has its bumps on the road just to see mothers face light up when they see the image of their unborn baby is such a breath taking experience. This all originated from going to one of my sisters’ ultrasound appointment that I ended up going to all my sisters’ ultrasound appointments.... [tags: Sonographer, Medical ultrasonography]

- Turner’s Syndrome Turner’s syndrome is a genetic conditions that affects the female’s sex chromosome. In (http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0001417/) Turner’s syndrome occurs when cells are missing all or part of an X chromosome. It’s common of the female patient to only have one X chromosome. Although, some individuals may have two X chromosomes but one is defective. It is thought that an estimated 1 out of 2000-2500 females suffer from this genetic condition worldwide but it’s usually females with this condition don’t survive their birth....

- In America alone there are 6.1 million couples coping with infertility (ASRM). In vitro fertilization (IVF) is one of the many assisted reproductive technologies used to help infertile couples achieve pregnancy. Since IVF is costly (the average cost is $12, 400. for one cycle), time consuming and a very emotional situation, many couples have a limited amount of opportunities to commit to the procedure and every step should be taken to maximize the chances of a successful healthy pregnancy. Preimplantation genetic diagnosis, or PGD, is a valuable tool for infertility treatment technology and can facilitate in successful IVF cycles.... [tags: Genetics]

Staff records, incoming and outgoing time of the staff, the holiday records of the staff, anything to do with the staff, are all examples of how computers are used in a medical office. If the doctor were to hand-write every little thing, to keep track of such things, it would be very difficult, but with computers, the task uses less time and the process is simplified....

- Child is a gift from God. Every parent hopes for a healthy child. However, abnormalities in the fetus growth becoming common nowadays. These may be due to physical, radiation and chemical factors. These factors will cause deformities such as genetic mutation which causes mental retardation, abnormal body buildup and other conditions which bring a lot of troubles in the future to the child themselves and their parents. Modern technologies and innovations in the medical field had developed a method to detect the abnormality before delivery and prevent this future tragedy to happen....

- Without the use of physics in the medical field today, diagnosis of problems would be challenging, to say the least. The world of medical imaging in particular has benefited greatly from the use of physics. Ultrasound is sound waves that have a frequency above human audible. (Ultrasound Physics and Instrument 111). With a shorter wavelength than audible sound, these waves can be directed into a narrow beam that is used in imaging soft tissues. As with audible sound waves, ultrasound waves must have a medium in which to travel and are subject to interference.... [tags: Physics, Ultrasounds, medical, ]

- The complexity of the human reproductive system is unbelievable baffling. The fact that the egg even leaves the protection of the ovary and starts its journey down the fallopian tube is remarkable. The process by which the sperm manage to scurry their way to meet the egg through the hostile environment of a woman’s body isanother great accomplishment of the human body. The fact that, in the majority of cases, the egg and sperm meet, join, and find their way into the uterus and set up the beginning of a new little life is one of the most perplexing “facts” of medical science....
